You people completely do not understand. There is no way any album/CD can make it past Friday. Albums released on Tuesday,of course have to be pressed and in boxes, shipped at least by express Saturday. In order for any of that to happen, the label has to have it….by/on Friday.
Even if an artist were to avoid all of that and release only digital, as soon as it is uploaded to the distributors (iTunes, Amazon, etc…) it’s as good as leaked. So unless an artist is willing to limit the distribution to digital only and limit any reviews or advanced press (also thustly limiting sales)they will always be leaked.
